High-speed four-edge sealing reciprocating tracking heat sealing mechanism

Abstract

The invention relates to the technical field of packaging machine equipment, in particular to a high-speed four-edge sealing reciprocating tracking heat sealing mechanism which comprises a conveying part arranged on a base, a reciprocating part and a heat sealing part synchronous with the reciprocating part. By arranging the conveying part, the reciprocating part and the heat sealing part which is kept relatively fixed with the reciprocating part, when the high-speed four-edge sealing reciprocating tracking heat sealing mechanism is in use, heat sealing treatment is carried out through the heat sealing part in the conveying process, and the reciprocating part and the conveying part can be kept relatively static within specific time, so that the heat sealing part can be in a working state in the process, heat sealing can be achieved in the running state of the conveying part, and the heat sealing efficiency is improved; and a plurality of annular sealing rings can be achieved in the heat sealing process in the mode that the inclined faces are arranged between two heat sealing plates to make contact, and the heat sealing effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of packaging machine equipment, in particular to a high-speed four-side sealing reciprocating tracking heat-sealing mechanism. Background technique [0002] Packaging machine is a kind of machine that packs products, which plays the role of protection and beauty. The existing packaging machines all use the method of fixing the heat-sealing device, and carry out heat-sealing treatment on the product in conjunction with the intermittent transportation of the product to be packaged, and because good sealing performance depends on the distance between the heat-sealing plate and the outer packaging of the product. In theory, the longer the time is, the better the heat-sealing effect is. Furthermore, in the prior art, when a fixed heat-sealing device is used to heat-seal a product, in order to obtain a good heat-sealing effect, it is necessary to ensure that the heat-sealing device and The contact time between th...

The existing packaging machines all adopt the method of fixing the heat-sealing device, and carry out heat-sealing treatment on the product in conjunction with the intermittent transportation of the product to be packaged, and because good sealing performance depends on the distance between the heat-sealing plate and the outer packaging of the product. In theory, the longer the time is, the better the heat-sealing effect is. Furthermore, when using a fixed heat-sealing device to heat-seal the product in the prior art, in order to obtain a good heat-sealing effect, it is necessary to ensure that the heat-sealing device and The contact time between the outer packaging of the product, during which the conveyors used to transport the product are at a standstill, resulting in less efficient packaging overall
